Experiment Background
Cashew is a native to Eastern Brazil and introduced into India by the Portuguese during the 16th Century and has now become one of the major dollar earning crops of India. In India, the cashew is cultivated on an area of about 10.11 lakh ha with annual production of 7.53 lakh tonnes of raw cashew nuts and productivity is 700 kg/ha. Although Andhra Pradesh has the largest area under cashew, Maharashtra ranks first in production and productivity. The area under cashew in Gujarat is 8000 hectare with production of 24,500 MT of raw nuts (Anon., 2015). The climatic condition of South Gujarat is similar to cashew grown area of the Maharashtra. But, there is lack of information about commercial production in the agro-climatic conditions of South Gujarat. Research results showed that tremendous positive response can be obtained through regular applications of fertilizers and improved management practices which could give two to three fold yield increases. Cashew especially high yielding hybrid varieties respond well to fertilizers, however, some researchers have found that productivity can be increased by foliar spray of macro and micronutrients (In addition to soil application). Foliar sprays of nutrients at emergence of the flush, panicle initiation and fruit set stages, ensure better fruit set and enhanced nut yield (Sapkal, 2000 and Anonymous, 2010; Ghose, 1990; Ankaiah and Rao, 1983). Cashew is grown in heavy rainfall area of West Coast especially on hill slopes. Most of the applied nutrients losses due to leaching and availability of nutrients might be low during critical stages that may adversely affected the growth, flowering, fruit set and yield of cashew. Therefore, foliar feeding of nutrient at different phenological stages (critical demand) may play the major role in increasing the fruit set, retention and overall production and quality of cashew by optimum uptake of nutrient with minimum losses. The present study is, therefore, planned to determine the effect of foliar application of fertilizers on flowering, yield and quality of cashew (Anacardium occidentale L.) cv. Vengurla-4
